Shortcut questions

SHORTCUT_QUESTIONS_TTL_MS

What it controls: how often the background generator refreshes per-(category, locale) dynamic shortcut questions on the Chat landing page. The endpoint always serves the cached batch; this knob is how stale "stale-but-served" can get.
Consumed by: src/shortcut-questions/refresh-loop.ts.
When to set: lower for faster turnover on news / trending topics, higher to cut LLM cost. Each refresh runs ~11 Haiku 4.5 calls per locale (~22 calls total at default settings).
Default: 21600000 (6 hours).
Format: positive integer milliseconds.
SHORTCUT_QUESTIONS_TTL_MS=21600000
Setting home: Not a user-facing setting

SHORTCUT_QUESTIONS_DISABLED

What it controls: skip the dynamic LLM generation entirely. The /v1/shortcut-questions endpoint still returns the hand-authored fixed lists; dynamic arrays stay empty.
Consumed by: src/shortcut-questions/refresh-loop.ts.
When to set: tests, cheap local dev without ANTHROPIC_API_KEY, or any environment where dynamic content isn't worth the spend.
Default: empty (dynamic generation enabled).
Format: 1 to disable. Anything else (including unset) leaves generation enabled.
